[antlr-interest] Re: Is antlr the right tool for this job?

[lgcraymer]

Two alternatives:  Either
1.) subclass ASTFactory and override create(AST) and create(Token) to
copy line and column info.

2.) use a custom AST class subclassed from CommonAST with
initialize(AST) and initialize(Token) overridden to copy the line and
column info.
